Re: [Dovecot] dovecot expire doesn't work (?)

Anybody has this working?

Yes.

plugin { expire = spamassassin/SPAM 1 expire_dict = proxy::expire }

For me it works by using '.' as hierarchy separator. So in your case expire = spamassassin.SPAM 1 should work. This could be different when using namespaces, which I don't.

That is, if I want to expire the emails under the spamassassin/SPAM directory, after 1 day. Is this correct? I'm asking this because with this setup, the expire-tool does nothing... nothing in the logs either.

Try and set mail_debug=yes. It should log more.
